A TTORNEYS Patented Nov. 11, 1930 NITED STATES PATENT OFFICE cas'r-s'ronn Tam BLOCK Application filed May 16,

This invention relates to walls and building blocks therefor.

In the construction of walls made from cement blocks it is frequently desirable to combine the cement blocks, or as they may be termed, ashlars, with one or more layers of bricks. Ordinarily there is much difficulty in bonding the brick to the cement block part of the wall because it is impractical and uneconomical to make the cement blocks of the same dimensions as the bricks, such blocks generally being several times as high and long as a brick of standard size. It is to be noted that bricks are now constructed,

almost without exception of a size of 2 4 by 4 by 8 inches.

One important object of the present invention is to provide an improved form of building block having such shape as to bond the wall constructed from such 'blocks to a facing substantially of brick.

A second important object of the invention is to provide a building block of cement or the like having arojection extending from one side face of su stantially the same shape and size as a standard brick.

A third important object of the invention is to provide certain of the building blocks thus cast with a projection of the same shape and size as a half brick, these last blocks being for corner construction.

A fourth important object of the invention is to provide an improved form of wall construction composed on one side of cement blocks and on the other side of bricks interfitted with projections on the cement blocks.

With the above and other objects in view as will be hereinafter apparent, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings and specifically claimed.

In the accompanying drawings like characters of reference indicate like parts in the several views, and:

Figure 1 is an outside perspective view of a Wall corner constructed in accordance with this invention.

1929. Serial No. 863,503.

Figure 2 is a view showing the inside of such a wall corner.

Figure 3 is a plan view of such a corner.

Figure 4 is a section on-the line 4-4 of Figure 3.

Figure 5 is a perspective View of one of the bricks of the main part of the wall.

F i'gure 6 is a perspective view of one of the special corner blocks.

Referring first to Figure 5 it will be seen that this block is provided with a body 10 and as this block is used in the body of the wall it is found desirable to make this body seventeen inches long, live and three-fourths inches high and four inches wide, From one side face of this block extends a rectangular projection 11. This projection is positioned centrally of the side and has its bottom face in the same plane as the bottom face of the body 10. Preferably this projection 11 is of the same size as a standard brick, that is to say it is eight inches long, projects outwardly four inches and is two and a half inches high. Thus the body, allowance being made for mortar, is two bricks 7 long, two bricks high and one brick Wide while the projection is one brick in length, width and thickness. In the form shown in Figure 6 there is disclosed a block intended for use at-the corner and this block has a body 12 and projection 13. The body 12 is twelve and five-eighths inches long, five and three-quarter inches high and four inches wide.

Thus in height and width it is the same as the body 10 so that it may follow the course laid by the side wall blocks 10 but it is only, allowance being made for mortar, one and a. half bricks long. The projection is three and five-eighths inches long, four inches wide and two and a quarter inches high. The projection thus'is substantially, allowance being xmade for mortar, thesame size asone half a standard brick.

As shown in the remaining figures the ce -ment blocks are laid in Flemish bond, each course being staggered with relation to the next preceding course so that similarly the projections 11 are staggered as can well be seen by reference to Figures 2 and 4. It will 1 be noted that each course of projections 11 is spaced from the preceding course a sufficient distance to permit of laying a continuous course of header bricks 14, the joints of such course coming centrally with relation to the projections 11 of the preceding course and the similar projections of the succeeding course. Also it will be seen from Figures 4 and 2 that interposed between adjacent projections 11 of the same course are bricks 15 which thus fill up the spaces and cause the inner face of the wall to be flush and even. At the corners it will be noted from Figures 3 and 2 that the projections 13 fill in the space between the adjacent projection 11 and the body of the corner block 12 just as would oc cur were ahalf brick used. Moreover, by this means it is rendered unnecessary to use but few half bricks in the construction of the wall since the brick that fits in the corner on the projection '13 will lap over the adjacent projection 11 to the center thereof as can be seen by reference to Figure 1. 7

Vith the wall as thus constructed a thorough bond is obtained between the cement block portion of the wall and the bricks and the whole wall thus forms a unitary structure upon the mortar setting so that each part thereof bears its proper share of the superposed load.

There has thus been provided a simple and eflicient device of the kind described and for the purpose specified.

It is obvious that minor changes may be made in the form and construction of the invention without departing from the material spirit thereof. It is not, therefore, desired to confine the invention to the exact form herein shown and. described, but it is desired to include all such asjiroperly come within the scope claimed.

Having thus described the invention, what is clai1ned as new, is: I

1. A wall construction consisting of a tier of courses of building blocks, the blocks in each course being staggered with respect to the blocks of the preceding course, each of said blocks being provided with a projection on one face, said projections being all positioned on the same face of the tier, bricks interposed between the. projections in each course, and other bricks interposed between the projections of one course and the projections of the succeeding course.

2. A wall construction consisting of a tier of courses of building blocks, the blocks in each course being staggered with respect to the blocks of the preceding course, each of said blocks being provided with a projection on one face, said projections being all positioned on the same face of the tier, bricks interposed between the projections in each course, and other bricks interposed between the projections of one course and the projections of the succeeding course, said projections being substantially equal in length and thickness to the bricks and of slightly greater width than said bricks.

3. A wall construction consisting of a tier of courses of building blocks, the blocks in each course being staggered with respect to the blocks of the preceding course, each of said blocks being provided with a projection on one face, said projections being all positipned on the same face of the tier, bricks interposed between the projections in each course, and other bricks interposed between the projections of one course and the projections of the succeeding course, said projections being substantially equal in length and thickness to the bricks and of slightly greater width than said bricks, the projections adjacent blocks of each course being slightly more than the length of one brick apart.

4. A wall construction consisting of a tier of courses of building blocks, the blocks in each course being staggered with respect to the blocks of the preceding course, each of said blocks being provided with a projection on one face, said projections being all positioned on the same face of the tier, bricks interposed between the projections in each course, other bricks interposed between the projections of one course and the projections of the succeeding course, said projections being substantially equal in length and thickness to the bricks and of slightly greater width'than said bricks, the projections adjacent blocks of each course being slightly more than the length of one brick apart, and a second wall at right angles to the first and including a tier of building blocks having projections equal substantially one half a brick in length and alined with the projew tions on the blocks of the first wall.

'In testimony whereof I afiix my signature.
